Hi Tapas,

A number of us are on vacation, including me. I will see if I can find time today or this weekend to look at it.

In the mean time, can you give us

1. a short list hostnames containing one manager, one supervisor and one data server.
2. attach xrootd configuration files from each of the above nodes?

regards,
